이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 블록형 옹벽 구조물의 섬유보강재를 도시한 도면이다. 도면을 참조하면, 본 발명에 따른 섬유보강재는 길이방향과 나란하게 복수의 마찰부(10)와 결속부(20)가 번갈아 배치되어 있다.1 is a view showing a fiber reinforcement of the block retaining wall structure according to the present invention. Referring to the drawings, the fiber reinforcing material according to the present invention are arranged alternately a plurality of friction portion 10 and the binding portion 20 side by side in the longitudinal direction.

마찰부(10)는 섬유보강재에 강성을 부여하기 위한 폴리에스테르계 섬유 심재(11)를 내장하고 있다. 심재(11)는 복수의 가닥으로 이루어지며, 각 가닥은 수천 가닥의 미세 섬유로 이루어져 있어서 섬유보강재에 작용하는 인장력에 효율적으로 저항한다. 심재(11)에는 폴리에틸렌계 합성수지로 이루어진 피복재(12)가 피복되어 있으며, 이 피복재(12)의 표면에는 요철(13)이 형성되어 흙과의 마찰력을 더욱 증가시킨다. The friction portion 10 incorporates a polyester fiber core 11 for imparting rigidity to the fiber reinforcement. Core material 11 is composed of a plurality of strands, each strand is composed of thousands of fine fibers to effectively resist the tensile force acting on the fiber reinforcement. The core member 11 is coated with a coating material 12 made of polyethylene-based synthetic resin, and irregularities 13 are formed on the surface of the coating material 12 to further increase the frictional force with the soil.

결속부(20)는 마찰부(10)의 피복재(12)와 같이 폴리에틸렌계 합성수지로 제조되며 섬유보강재를 둘러싸고 있는 상하측의 흙이 서로 접촉되도록 함으로써 흙 간의 결합력을 증대시킨다. 이를 위해, 결속부(20)는 섬유보강재의 길이방향을 따 라 소정 간격으로 천공홀(21)을 구비한다. 천공홀(21)의 길이(H)는 천공홀간 이격거리(S)의 2배이며, 폭(W)은 천공홀간 이격거리(S)의 0.5배이다. 길이(H)가 너무 길거나 이격거리(S)가 너무 짧거나 폭(W)이 너무 넓으면 횡방향으로 작용하는 힘에 취약하여 결속부(20)가 찢어지는 경우가 발생한다. 천공홀(21)의 모서리는 응력을 분산시킬 수 있도록 라운딩처리된다. The binding unit 20 is made of a polyethylene-based synthetic resin, such as the coating member 12 of the friction portion 10 and increases the bonding force between the soil by making the upper and lower soils surrounding the fiber reinforcement contact each other. To this end, the binding unit 20 is provided with a punched hole 21 at predetermined intervals along the longitudinal direction of the fiber reinforcement. The length H of the boring holes 21 is twice the spacing distance S between the boring holes, and the width W is 0.5 times the spacing distance S between the boring holes. If the length H is too long, the separation distance S is too short, or the width W is too wide, the binding part 20 may be torn due to being vulnerable to the force acting in the lateral direction. The corners of the drilling holes 21 are rounded to disperse the stress.

마찰부(10)와 결속부(20)는 단차를 가지되, 바람직하게는 결속부(20)가 마찰부(10)보다 낮은 높이를 가진다. 이것은 결속부(20)에 흙이 상대적으로 더 채워짐으로써 상대적으로 흙의 하중을 천공홀(21)에 더 집중시켜 접촉하는 흙 간의 결합력이 더욱 증대시킨다. The friction part 10 and the binding part 20 have a step, but preferably, the binding part 20 has a height lower than that of the friction part 10. This is because the soil is more relatively filled in the binding unit 20, the load of the soil is relatively more concentrated in the drilling hole 21 to further increase the bonding force between the soil in contact.

섬유보강재는 복수개가 적층되어 사용될 수도 있다. 이때는 겹쳐지는 천공홀(21,21')이 도 1에 점선으로 표시한 바와 같이 교호 상태가 되도록 배치하는 것이 바람직하다. 그리고, 섬유보강재는 나란히 배치되는 복수의 마찰부(10)와 결속부(20) 사이에 절취부(30)를 구비하여 필요한 인장강도에 따라 간편하게 분리해서 사용할 수 있도록 할 수 있다. Fiber reinforcement may be used in a plurality of laminated. At this time, it is preferable that the overlapping perforation holes 21 and 21 'are arranged so as to be in an alternating state as indicated by a dotted line in FIG. In addition, the fiber reinforcing material may be provided with a cutout portion 30 between the plurality of friction portions 10 and the binding portion 20 arranged side by side, so that the fiber reinforcement may be easily separated and used according to the required tensile strength.

도 2는 상술한 본 발명에 따른 섬유보강재를 제조하는 방법을 도시한 도면이다. 도면을 참조하면, 섬유보강재(1)는 이중사출부(100)와, 압착성형부(200)와, 냉각부(300)와 프레스부(400)와 인발부(500)와 권취부(600)를 통해 제조된다.Figure 2 is a view showing a method for manufacturing a fiber reinforcement according to the present invention described above.

The double injection part 100 is for coating the synthetic resin coating material 12 on the fiber yarn entering the friction part 10, the double injection mold 110 enters the fiber core material 11, the yarn agglomerated on one side and pellets on the other side The molten resin in which the synthetic resin is dissolved is supplied from the injection machine 120.

압착성형부(200)는 섬유 심재(11)를 내장한 피복재(12)의 외형을 성형하기 위한 것으로서, 압착롤러(210)를 사용한다. 압착롤러(210, 제1압착롤러)의 외주에는 본 발명의 섬유보강재를 형성할 수 있도록 마찰부(10)와 결속부(20) 형태가 가공되어 있다. 본 실시예에서는 압착롤러(210)의 후방에는 보조압착롤러(220, 제2압착롤러)를 더 구비한다. 보조압착롤러(220)는 결속부(20)를 얇게 가공하기 위한 것으로, 전방의 압착롤러(210)에서 결속부(20)를 얇게 가공하게 되면 섬유보강재의 형태가 찌그러지기 쉽기 때문에 2차에 걸쳐 가공한다.The compression molding part 200 is for molding the outer shape of the coating material 12 in which the fiber core 11 is incorporated, and uses the compression roller 210. In the outer circumference of the compression roller 210 (first compression roller), the friction portion 10 and the binding portion 20 are processed to form the fiber reinforcing material of the present invention. In the present embodiment, the rear of the pressing roller 210 is further provided with an auxiliary pressing roller 220, the second pressing roller. The auxiliary compression roller 220 is for processing the binding unit 20 thinly, and when the binding unit 20 is thinly processed in the front compression roller 210, the shape of the fiber reinforcing material is easily crushed over the second Processing.

냉각부(300)는 고열 상태로 성형되는 섬유보강재(1)의 열을 식히기 위한 것으로서, 연속적으로 공급되는 섬유보강재(1)를 효율적으로 냉각시킬 수 있도록 수냉식 탱크(310)에 침적시킨다. 탱크(310)의 물은 지속적으로 순환한다. 탱크(310)의 후단에는 섬유보강재(1)에 붙어 있는 물기를 제거할 수 있도록 에어브러쉬(320)가 횡방향으로 마련되어 있다.The cooling unit 300 is for cooling the heat of the fiber reinforcement 1 molded in a high temperature state, and is deposited in the water-cooled tank 310 to efficiently cool the fiber reinforcement 1 continuously supplied. The water in tank 310 continually circulates. At the rear end of the tank 310, the airbrush 320 is provided in the lateral direction so as to remove moisture adhering to the fiber reinforcement (1).

프레스부(400)는 마찰부(10)와 결속부(20)가 성형된 섬유보강재(1)의 결속부(20)에 천공홀(21)을 형성하기 위한 것으로서, 다양한 폭이 요구되는 섬유보강재(1)의 특성에 따라 구비된 금형(410)을 미리 설치하여 연속적으로 천공홀(21)을 펀칭할 수 있도록 한다. The press unit 400 is for forming the punched hole 21 in the binding portion 20 of the fiber reinforcing material 1 in which the friction portion 10 and the binding portion 20 are molded, and the fiber reinforcing material having various widths is required. The mold 410 provided according to the characteristic of (1) is installed in advance so that the punching hole 21 can be continuously punched.

인발부(500)는 가공 중인 섬유보강재(1)를 효과적으로 포장할 수 있도록 공정 중의 섬유보강재(1)를 권취기(600)로 당겨주는 역할을 한다. 인발부(500)로는 무한궤도로 회전하는 캐터필러가 바람직하다.The drawing part 500 serves to pull the fiber reinforcement 1 during the process to the winding machine 600 to effectively package the fiber reinforcement 1 being processed. As the drawing part 500, a caterpillar rotating in an infinite orbit is preferable.

한편, 도 4는 본 발명에 따른 섬유보강재를 연약 지반의 침하를 방지하기 위한 지오그리드로 활용한 일례를 예시한 도면이다. On the other hand, Figure 4 is a view illustrating an example of using the fiber reinforcement according to the invention as a geogrid for preventing the settlement of the soft ground.

도시된 바와 같이, 본 발명의 섬유보강재(1)를 복수 개 옆으로 배치한 후 상호 인접하는 결속부(20)의 천공홀(21,21')들을 결합부재로 연결하게 되면 직물 형태의 지오그리드가 형성된다. 섬유보강재(1)의 연결은 강도가 높으며 부식되지 않는 스텐레스 재질의 클립(40)을 이용하며, 클립(40)은 양단을 이웃하는 섬유보강재의 각 천공홀(21,21')에 걸은 후 압착하여 섬유보강재에 고정시키게 된다. 이와 같이 마련된 섬유보강재 지오그리드를 연약 지반에 넓게 시공하게 되면, 성토의 결합력이 지오그리드의 천공홀(21,21')들을 통해 증가되면서 지반의 침하를 효율적으로 방지하게 된다.As shown, when the plurality of fiber reinforcement (1) of the present invention is disposed sideways and then connecting the drilling holes (21, 21 ') of the adjacent coupling unit 20 with the coupling member geogrid of the fabric form Is formed.
